Biogas and bio-methane that are based on energy crops are renewable energy carriers and therefore potentially contribute to climate protection. However, significant greenhouse gas emissions resulting from agricultural production processes must be considered. Among those, the production and use of fertilizer, and the resulting leaching of nitrous oxide (N2O) are crucial factors. This paper provi...

to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...

Soil fertility can be potentially improved and degradation retarded by replacing some of the chemical fertilizer with bio-fertilizer (BF). To optimize such change, BF was applied at substitution ratios 0% (BF0), 30% (BF30), 50% (BF50), 70% (BF70), 100% (BF100) in a field experiment 2018 2019. organic carbon (C) contents, stability, C contents aggregate fractions were determined 0–20 cm layer.

Liquid animal manure and its management contributes to environmental problems such as, global warming, acidification, and eutrophication. To address these environmental issues and their related costs manure processing technologies were developed. The objective here was to assess the environmental consequences of a new manure processing technology that separates manure into a solid and liquid fr...
